Look at page in Chrome for iOS: loads, then suddenly switches to App Store due to ad that loads with app store link, which is the mobile device equivalent of a pop up ad.

Look at page in the Facebook app: get messahe that a link is trying to leave the Facebook app, do I want to?

The Facebook app is better than the web browsers for the app links !!

Oh good, you're still alive. You never got my private Plurk...?
